Improving yield in semiconductor manufacturing

Demand for semiconductor wafers will continue its vigorous growth as the demand for mobile devices, cloud computing, Internet of Things (IoT), automotive, artificial intelligence, and other uses increases. The complexity of the processes and costs of semiconductor fabrication (FAB) manufacturing are high, so those in the industry is always looking to improve production efficiencies.

The key to improving production efficiency is to ensure the highest wafer yield possible. As Figure 1 implies, yield is affected at every stage in the process—from design to final assembly and packaging. Yield is affected by the individual process steps (500-1500) but also by the quality of the manufacturing environment to which the wafers are exposed, including clean room air, ultrapure water (UPW), chemicals and inert and reactive gases.
